The STMicroelectronics STTA112U is an ultra-fast, high voltage diode belonging to the TURBOSWITCH family. It is specifically designed for applications requiring extremely fast, soft, and noise-free power diodes, such as snubbing, clamping, demagnetization, and rectification.
Key electrical characteristics include a repetitive peak reverse voltage (VRRM) of 1200V and an average forward current (IF(AV)) of 1A. The diode exhibits a fast recovery time (trr) of 65ns typical, contributing to very low overall power losses in both the diode and companion transistors. Its forward voltage drop (VF) is 1.1V typical at 1A and 25°C.
This diode is suitable for high-frequency operation and offers high reverse voltage capability. It is particularly beneficial in motor control circuitries and the primary or secondary sides of Switched-Mode Power Supplies (SMPS). The optimized switching performance also decreases power losses in associated switching IGBT or MOSFET devices during freewheel operations.
The STTA112U is housed in a Surface Mount SMB package (DO-214AA), making it suitable for compact designs. It operates at a maximum junction temperature of 125°C.
